ABSTRACT

Substituted triazolinone compounds of the formula: 
                 
 
wherein the variables R 1 , R 2 , R 7 , R 8 , R 12  and X are as defined in the specification are useful as herbicides, plant growth regulators, insecticides and acaricides. Processes for the preparation of these compounds, and intermediates useful in such preparation are also disclosed.

This application is an continuation-in-part of U.S. Ser. No. 08/148,094, filed on Nov. 5, 1993, now abandoned; and also a continuation-in-part of U.S. Ser. No. 07/918,895, filed on Jul. 20, 1992, now U.S. Pat. No. 5,554,580, which is, in turn, a continuation of U.S. Ser. No. 07/618,335, filed on Nov. 26, 1990, now abandoned, which is, in turn, a division of U.S. Ser. No. 07/435,898, filed on Nov. 13, 1989, now U.S. Pat. No. 5,006,148.

The invention relates to novel N-aryl-substituted nitro-gen-containing heterocycles, several processes and novel intermediates for their preparation, and their use as herbicides and plant growth regulators. The triazolinone compounds further have a utility as an insecticide or as an ascaricide (cf patent application Ser. No. 08/148,094) disclosure herein incorporated by reference.

It is known that certain N-aryl-substituted nitrogen-containing heterocycles, such as, for example, the compound 1-(2-chloro-4-trifluoromethylphenyl)-5-methyl-4-nitropyrazole, possess herbicidal properties (cf., for example, European Patent 200,872).

Likewise has been disclosed that certain substituted triazolinones such as, for example, the compound 3,4-dimethyl-1-(3-fluoro-4-cyano-phenyl)-1,2,4-triazolin-5-one or the compound 3-methyl-4-propargyl-1-(2,5-difluoro-4-cyano-phenyl)-1,2,4-triazolin-5-one have herbicidal properties (cf., for example, U.S. Pat. No. DE 3,839,480).

However, the herbicidal activity of these previously known compounds against problem weeds, as well as their tolerance by important crop plants, are not entirely satisfactory in all fields of application.

Nothing has been known to date about a plant growth-regulating effect of the previously known compounds.

The active compounds according to the invention can be used as defoliants, desiccants, agents for destroying broadleaved plants and, especially, as weed-killers. By weeds, in the broadest sense, there are to be understood all plants which grow in locations where they are undesired. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.

The active compounds according to the invention can be used, for example, in connection with the following plants:

Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver and Centaurea.

Dicotyledon cultures of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita.

Monocotyledon weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera.

Monocotyledon cultures of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hopfields, and for the selective combating of weeds in annual cultures.

Here, the active compounds of the formula (I) and (Ia) according to the invention can be employed with particularly good success for combating dicotyledon weeds in monocotyledon and dicotyledon crops, such as, for example, soya or wheat. The intermediates of the formula (X) also possess a good herbicidal activity.

The active compounds according to the invention furthermore engage in the metabolism of the plants and can therefore be employed as growth regulators.

Experience to date of the mode of action of plant growth regulators has shown that an active compound can also exert several different actions on plants. The actions of the compounds depend essentially on the point in time at which they are used, relative to the stage of development of the plant, and on the amount of active compound applied to the plants or their environment and the way in which the compounds are employed. In each case, growth regulators are intended to influence the crop plants in the particular manner desired.

The amount of leaf on plants can be controlled, under the influence of growth regulators, so that defoliation of the plants at a desired point in time is achieved. Such defoliation is of great importance in the mechanical harvesting of cotton, but is also of interest for facilitating harvesting in other crops, such as, for example, in viticulture. Defoliation of the plants can also be carried out to lower the transpiration of plants before they are transplanted.

The active compounds of formula (IA) are furthermore suitable for combating animal pests, perferably arthropods and nematodes, in particular insects and arachnids, encountered in agriculture, in forestry, in the protection of stored products and of materials, and in the hygiene field.

The active compounds according to the invention are distinguished by a powerful insecticidal and acaricidal activity. They can be used particularly successfully for combating the greenhouse red spider mite (Tetranychus urticae). Besides, the active compounds have, in particular, leaf-acting insecticidal properties.

Depending on their particular physical and/or chemical properties, the active compounds can be converted to the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, natural and synthetic materials impregnated with active compound, very fine capsules in polymeric substances. When appropriate the active compounds can be used in coating compositions for seed, furthermore in formulations used with burning equipment, such as fumigating catridges, fumigating cans, fumigating coils and the like, as well as ULV cold mist and warm mist formulations.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, liquefied gases under pressure, and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents. In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example mineral-oil fractions, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, as well as water; by liquefied gaseous extenders or carriers are meant liquids which are gaseous at ambient temperature and under atmospheric pressure, for example aerosol propellants, such as halogenated hydrocarbons as well as butane, propane, nitrogen and carbon dioxide; as solid carriers there are suitable: for example ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates; as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example non-ionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as well as albumen hydrolysis products; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.

Mixtures with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repellants, plant nutrients and agents which improve soil structure, are also possible.

When used as herbicides, the active compounds can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are used in the customary manner, for example by watering, spraying, atomizing or scattering.

When used as herbicides, the active compounds according to the invention can be applied either before or after emergence of the plants.

They can also be incorporated into the soil before sowing.

When used as herbicides, the amount of active compound used can vary within a substantial range. It depends essentially on the nature of the desired effect. In general, the amounts used are between 0.01 and 10 kg of active compound per hectare of soil surface, preferably between 0.05 and 5 kg per hectare.

The insecticides include, for example, phosphates, carbamates, carboxylates, chlorinated hydrocarbons, phenylureas and substances produced by microorganisms.

When used as insecticides and acaricides, the active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergistic agents. Synergistic agents are compounds which increase the action of the active compounds, without it being necessary for the synergistic agent added to be active itself.

The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95 percent by weight of active compound, preferably between 0.0001 and 1 percent by weight.

When used as insecticides and acaricides, the compounds are employed in a customary manner appropriate for the use forms.

When used as growth regulators, the active compounds according to the invention can be present in the formulations also as a mixture with other known active compounds, such as fungicides, insecticides, acaricides and herbicides, and also as mixtures with fertilizers and other growth regulators.

The active compounds can be used as such, in the form of their formulations or as the use forms prepared therefrom, such as ready-to-use solutions, emulsifiable concentrates, emulsions, foams, suspensions, wettable powders, pastes, soluble powders, dusting agents and granules. They are used in the customary manner, for example by watering, spraying, atomizing, scattering, dusting, foaming, coating and the like. Furthermore, it is possible to apply the active compounds in accordance with the ultra-low volume process or to inject the active compound preparation or the active compound itself into the soil. It is also possible to treat the seeds of plants.

When the compounds are used as plant growth regulators, the amounts applied can also be varied within a substantial range. In general, 0.01 to 50 kg, preferably 0.05-to 10 kg, of active compound are used per hectare of soil surface.

As far as the time of application is concerned, the application of the growth regulators is carried out in a preferred period, the exact limits of which depend on the climatic and vegetative conditions.

-   -   (disclosed in EP-A 200,872/Example 19)

Example A

Pre-Emergence Test

-   Solvent: 5 parts by weight of acetone -   Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.

Seeds of the test plants are sown in normal soil and, after 24 hours, watered with the preparation of active compound. It is expedient to keep constant the amount of water per unit area. The concentration of the active compound in the preparation is of no importance, only the amount of active compound applied per unit area being decisive. After three weeks, the degree of damage to the plants is rated in % damage in comparison to the development of the untreated control. The figures denote:

-   -   0%=no action (like untreated control)     -   100% total destruction

In this test, for example the compounds of Preparation Examples 10, 14, 16, 17, 18 and 23 are clearly superior to the prior art, with respect to both effectiveness and crop plant selectivity.

Example B

Post-emergence Test

-   Solvents 5 parts by weight of acetone -   Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.

Test plants which have a height of 5-15 cm are sprayed with the preparation of the active compound in such a way as to apply the particular amounts of active compound desired per unit area. The concentration of the spray liquor is so chosen that the particular amounts of active compound desired are applied in 2,000 l of water/ha. After three weeks, the degree of damage to the plants is rated in % damage in comparison to the development of the untreated control. The figures denote:

-   -   0%=no action (like untreated control)     -   100%=total destruction

A clearly superior effectiveness as well as crop plant selectivity, compared with the prior art, is shown in this test for example by the compounds of the following Preparation Examples: 9, 10, 12, 14, 16, 17, 18, 23 and 44.

Example C

Defoliation and Desiccation of the Leaves of Cotton

-   Solvent: 30 parts by weight of dimethylformamide -   Emulsifiers 1 part by weight of polyoxyethylene sorbitan monolaurate

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amounts of solvent and emulsifier and the mixture is made up to the desired concentration with water.

Cotton plants are grown in a greenhouse until the 5th true leaf has unfolded completely. In this stage, the plants are sprayed with the preparations of active compound until dripping wet. After 1 week, the shedding of leaves and the desiccation of the leaves are rated, in comparison with the control plants.

The figures of merit have the following meanings:

-   -   0 denotes no desiccation of leaves, no shedding of leaves     -   +denotes slight desiccation of the leaves, slight shedding of         leaves     -   ++denotes severe desiccation of the leaves, severe shedding of         leaves     -   +++denotes very severe desiccation of the leaves, very severe         shedding of leaves.

A clear superiority compared with the untreated control is shown in this test for example by the compounds of the following Preparation Examples: 13 and 16.

Example A

Pre-emergence Test

-   Solvent: 5 parts by weight of acetone -   Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, one part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.

Seeds of the test plants are sown in normal soil and, after 24 hours, watered with the preparation of the active compound. It is expedient to keep constant the amount of water per unit area. The concentration of the active compound in the preparation is of no importance, only the amount of active compound applied per unit area being decisive. After three weeks, the degree of damage to the plants is rated in % damage in comparison to the development of the untreated control.

The figures denote:

-   -   0%=no action (like untreated control)     -   100%=total destruction

While Comparison Example (A) exhibits no herbicidal activity against weeds such as Setaria, Amaranthus, Chenopodium, Galinsoga, Matricaria, solanum and Viola, at an application rate of 250 g/ha, activities between 40 and 100% are shown, in this test, for example, by the compounds of Preparation Examples 57, 59, 67 and 79 and activities between 95 and 100% by the compounds of Preparation Examples 60, 61, 62, 65 and 69.
